In theory you could locate the AUDIO pin from the back of the mic jack, and add a resistor from there to the center pin of the ext speaker jack in the same manner as you would a PA jack.  But look into more before you do as I have never done it that way and Unidens sometimes have a funky way of wiring their boards.  If I had one laying around I would try it out but I don't.  best of luck!

    Solder one end of a 180 to 200 ohm half watt resistor to the negative pin of the External Speaker Jack (on the pc board). Solder the other end to the chasis of the radio. This wont do anything harmful to the radio. It will give you talk back. If the volume of the talk back is too low, reduce the value of the resistor until you have a comfortable level. Keep in mind that if you reduce the value too much, you will get feedback from the speaker that will drive you and everyone else crazy. If you get the volume correct and have a bit of feedback, you can connect a low value electrolytic capacitor (2.2 uF) across the speaker leads to filter off some high frequencies and reduce or stop the feedback. This works on MOST Cobra and Uniden CB's as well as mant Cybernette CB's like Lafayette, Colt and HyGain. Brands

I Want To Add Talk Back Mod To CB Radio


there is what is known as the Quick and Dirty way, to add talkback to almost any CB radio. You will need a 130 Ohm 1/4 watt resistor. Open the radio and find the two mounting points for the external speaker jack and PA audio jack, you will want to solder the resistor across from the Positive connection of the PA jack to the Ground connection for the External speaker jack. This will give you talkback, and eliminate any feedback when the microphone is held at a normal operating distance away, Just remember, (This could potentially damage your radio if done improperly, I will not be held liable for anything that you do to your radio.) However, when done correctly this is a perfectly safe modification, and will allow you to monitor your output audio, as it is being transmitted. You can adjust the size of the resistor to your liking, however, I do not recommend anything lower than 100 Ohm, as there will be more potetial for squealing/feedback.

I want talkback on cobra 18 WX ST


Probably to Chassis Ground. You may want to experiment with the resistor value if you use a power mic. A 100 Ohm resister may be too low a value and cause audio feedback if you do use a power mic.

I have a Cobra 29 WX NW BT and i can not receive any transmisions unless the other CB user is right beside me. If they move more then a car lenght away i can see the signal come in but no voice. Also my PA...


You have a bad microphone. There is most likely a broken wire in the microphone jack.

Without a microphone the radio will not go into receive mode, at all. Same thing happens when there is a disconnected wire in the mic cord. Because the radio you have, has Talkback in it, you can always hear a little audio coming through, but not a lot.

Try a new mic or one you know is good.

I want talkback on my cobra 29ltd classic radio how do i do this myself


Open the case on your radio. Solder a 100 ohm resistor between the pa jack and ext speaker jack. You can add a switch if you like to turn it on and off. The lower the resistance, the louder the talkback.

WANT TO ADD TALKBACK IN A RADIO


A 200 ohm 1-watt resistor across pins 1 & 4 of the mic jack will make some talkback. More or less resistance will make less or more talkback. Note the association of less and more.
